Meanwhile, the Sony remote control has always had more Funktionsaufälle from my parents, especially the lower buttons (volume, program back and forth, Mute) have not stopped working.
On the Internet I came across a tutorial, after which the remote control is opened and the interior should be cleaned with ethanol. After initial problems as this was not too difficult to implement and see which keys have again work - at least for a day ...
So we decided it to buy a new remote control.
The choice fell on the RM-ED011.
Since about 1 week this is now in operation and we are excited:
+ Pressure point almost perfect
+ Hassle of "targets" no longer necessary, like the remote control can even show up at the ceiling, the function is executed anyway
+ Processing very good
+ Remote control is somewhat narrower, lighter and shorter than the RM-ED035, but is very good in the hand, which of course is always a matter of opinion
Conclusion:
A perfect remote control supplied with 25,80 by almost half cheaper than the original remote control for the Sony Bravia KDL-40Z5800 TV.
Therefore, absolute buy recommendation !!!
PS: When I think, I'll check after about 1 year, if the satisfaction is still present, as currently.
